Tenpower INR21700-60XG 6000mAh 3.6V High Power Lithium Ion Cell Max 60A Continuous Discharge 160A 3s Pulse Low Internal Resistance ≤5mΩ For E-bike Scooter Power Tool Energy Storage Battery Pack

Core Selling Points
✅ Super Large Capacity & High Energy Density
- Nominal capacity: 6000mAh, minimum guaranteed capacity ≥5900mAh
- Single cell energy: 21.6Wh, gravimetric energy density ~284Wh/kg
- Lightweight design: max cell weight only 76.0g, effectively reduce total battery pack weight
- Standard 21700 size: Diameter ≤21.50mm, Height ≤70.50mm, compatible with mainstream pack structural design
✅ Ultra Low Internal Resistance, Less Heat Generation
- Internal impedance ≤5mΩ (tested at 1kHz AC, 25±3℃, 30% SOC)
- Low IR brings tiny voltage drop under heavy load, low heat accumulation during continuous high-current discharge
- Avoid thermal runaway risk for long-time high-power operation, extend whole pack service life
✅ Top-Tier Heavy Discharge Capability (Core Advantage)
- Continuous Discharge Current
- 40A steady discharge without temperature protection cut-off
- Max 60A continuous discharge with built-in 75℃ thermal cut-off protection
- Instant Pulse Output: 160A peak pulse discharge sustain for 3 seconds, great for startup surge power demand
- Excellent Rate Capacity Retention (Reference: 5900mAh @0.2C=100%)10A:94% | 20A:95% | 30A:95% | 40A:93% | 50A:92%
Even under 50A heavy load, still reserve 92% rated capacity without obvious power attenuation
✅ Wide Temperature Discharge Performance
- -20℃: retain 90% capacity, stable power supply for cold climate outdoor equipment
- 60℃: full 100% capacity output, suitable for high-temperature working environment
✅ Reliable Heavy-Duty Cycle Life
Standard cycle test condition (25℃ room temperature):
6A CCCV charge to 4.2V (100mA cut-off) → rest 10min → 40A constant discharge to 2.5V or 75℃ cut-off → rest 45min as one full cycle
After 500 complete heavy-duty cycles, capacity retention ≥60% of initial discharge capacity, durable for frequent charge-discharge cycle equipment
✅ Comprehensive Safety & Mechanical Reliability
- Electrical safety test: 3C overcharge to 10V, external short-circuit test
- Mechanical safety test: 13kN crush test, triaxial vibration, 75G mechanical impact
- Thermal safety test: 130℃ thermal shock bake for 10 minutesStrict raw material inspection & full finished cell aging test before delivery, ensure batch consistency & safety.
✅ Convenient Assembly & Storage Performance
- Negative bottom with Φ3.5mm prohibited welding area, standard spot welding assembly, soldering directly on cell shell forbidden
- Delivery state: SOC<30% low charge status, convenient for sea/air transportation, comply with lithium battery shipping rules
- Storage humidity ≤60%, flexible storage window:1 month: -20℃~60℃ | 3 months: -20℃~45℃ | 12 months long-term storage: -20℃~25℃
Factory ex-factory cell can recover ≥90% standard capacity after long storage
